Honestly we were having some issues where the configuration wasnt loading right after a reboot. It would parse valid lines out of the config. You could manually reinsert them though. It was quite strange.

I was having issues configuring anyconnect for voip and I thought it was because of my version. Turns out, tac sent me config example for a router and not asa which is why the commands didnt match up. Specifically crypto ca vs crypto pki.

8.2 to 8.3 is considered a major upgrade, something with the restructuring of the NAT configurations. I just upgraded one of our ASA's from 8.2 to 8.3. We've been running it for about 3 months now without any issues from what I can tell. I'm in the process now of upgrading our second ASA which we are running the CAC VPN on, that was a pain to duplicate on the replacement ASA but a sense of accomplishment when it finally worked!

It seems we will be holding off on the 8.4 upgrade until it has been out for a bit.

I've only been in the networking game since the end of 2009 and I only have a CCENT so take it however
